Check your partitions with command:
Lets mount our /dev/sdb1 disk partition with ext3 filesystem to mount point /mnt/sdb1:
mount -t ext3 /dev/sdb1 /mnt/sdb1
we can now use -o remount option to remount it with read only permitions only:
mount -o remount,ro /dev/sdb1
To mount it back with read & write permitions:
mount -o remount,rw /dev/sdb1
With mount command we can mount all kinds of filesystem. For example to mount ISO image we can do:
mount -t iso9660 myiso.iso /mnt/cdrom -o loop
ISO image is now available from /mnt/cdrom direcotry.
